This two-story maisonette anchors a corner spot in an iconic Upper East Side co-op at 810 Fifth Avenue. Asking $14,995,000, the home combines the expansive private living you’d find in a Manhattan mansion with the white-glove service of a pre-war co-op. As recently featured in the New York Times, the Renaissance Palazzo-style 1926 building, designed by noted architect J.E.R. Carpenter, has been home to bold-faced names from William Randolph Hearst, Richard Nixon, and Nelson Rockefeller to David Geffen and Charles Bronfman. The 5,600-square-foot duplex was most recently the pied-à-terre of billionaire investor and philanthropist David H. Murdock, who died last year at 102.

The two-floor home, among the building’s largest units, is on the market for the first time in 40 years. The duplex boasts five bedrooms, six full baths, exposures on all sides for endless natural light, and Central Park views. The ground-floor unit’s opulent interiors include upholstered walls, brass chandeliers, and lots of mirrors.

A sweeping entry gallery leads to the lower-level entertaining rooms. An intimate library and elegant dining room are complemented by a large upstairs salon and music room. Each public room has classic pre-war character, anchored by a wood-burning fireplace.

An eat-in kitchen with updated appliances is joined by a breakfast room for casual dining. Highlights include wine storage and a massive prep island.

On the second level, an exceptionally private primary suite boasts another wood-burning fireplace along with an oversized en-suite bath and generous closet space. Each of the four more bedrooms gets use of a full bath. For added convenience, there’s a dedicated laundry room, a service entrance, and storage galore.

Located across the street from Central Park and steps from Madison Avenue shopping, the building remains one of Fifth Avenue’s most coveted addresses. White glove services—like a full-time doorman—assure a rare level of safety, security, and privacy.
